Added local shader array initializer

[Chaosus]

Continuation of #30500

Also added deducted initializer for the array

instead of

float test[3] = float[3] (0.0, 1.0, 1.0);

user can write

float test[3] = {0.0, 1.0, 1.0};

Also added third init form which is

float t[] = { 0.0, 0.0, 1.0 };

In that case array size is deducting from the argument count inside the curly brackets

Ok, I think its a bug-free. In the next step I would probably implement an inout array parameters in functions..
